M555 Installation Requirements
The installation of the M555 shall comply with all local and national re and electrical codes,
i.e. NFPA 70, National Electric Code. In order to provide proper re and electrical shock pro-
tection, the M555 shall be powered from an isolated power source, use 14 AWG supply wiring
provided with an 8A over current protection fuse. The fuse shall be located at the secondary of
the source to properly protect the power supply secondary conductors. Field wiring shall use
60°C copper conductors. The wire should be stripped 0.310” and the terminal block tightened
to the recommended torque, 0.79 N-m (7.0 lb-in.) DC control signals should be segregated
from AC power and AC control wiring by using separate wire ducts and separate conduit.
The M555 is an open type device that requires an appropriate enclosure, suitable to the instal-
lation site. The surrounding air temperature of the M555 should not exceed 50°C (122°F).
